I was playing with it last month and whipped up a simple "toy" (calling it a "game" is too much) that lets me fly a little space ship around a little asteroid field. It took about a day to get it working enough to be fun. (I polished it up a little after that, and maybe one day I'll add some actual game play, mine an asteroid, whatever.)

While I used GDScript there's a node & pipe dataflow visual UI that non-programmers can use to construct "code", so I think it counts as low-code. You can modify your objects to "export" member vars to the UI so you can tweak them with widgets.
If I had to e.g. design and deploy a 3D world for VR users I would seriously consider Godot as a front-end IDE.
(BTW, I also made a fun knock-down-the-tower toy I call Yengapult: https://git.sr.ht/~sforman/Yengapult )
